Why You’re Obsessed With True Crime: A Nervous System Deep Dive


Listen Later

Why do millions of people relax to murder documentaries? Why does danger feel calming? In this episode, we break down the exact neuroscience behind true crime obsession: predictive processing, hypervigilance, closure-seeking dopamine cycles, attachment styles, and how the nervous system uses fear simulations to create a sense of safety.

This isn’t morbid curiosity — it’s survival wiring. Your body is studying danger, rehearsing responses, validating intuition, and completing emotional cycles your real life never allows.

We dig into:

  • Why your nervous system craves predictable fear over unpredictable calm
  • How observational learning and vicarious rehearsal train the brain
  • Why childhood chaos makes true crime feel familiar
  • The dopamine “resolution loop” that keeps you binge-listening

Once you understand what your true crime habit is doing for your nervous system, everything finally makes sense.
